Abelias have been a landscape staple in the Southeastern United States for over a century. Numerous types have been used over the years, but two of the oldest forms still used in landscapes are Glossy Abelia Abelia x grandiflora and Abelia ‘Edward Goucher’, dating back to the early 1900s.
Glossy Abelia is a large informal shaped shrub with ½ – 1 inch glossy green leaves and large clusters of tiny white flowers. It can grow to 8 feet wide and tall and tolerates tough landscape sites such as full sun, low moisture (once established), acidic or slightly alkaline soils. It blooms prolifically and is attractive to butterflies and pollinators. New stems are reddish colored which contrasts nicely with dark green foliage which may be evergreen if winters are mild. After blooms are spent the pink sepals remain on the plants carrying more color through the season.
‘Edward Goucher’ Abelia does not grow quite as large and is a good performer with pink flowers. It is smaller than Glossy Abelia, but can still reach 5’x5’ when mature. It is also tolerant of hot, dry spots in the landscape.
Over the past few decades there have been many new introductions of abelia cultivars to the market. A major goal of breeders was to offer abelias that would fit into smaller landscapes and there has also been a trend towards variegated foliage color. There are dozens of abelias in production, but a few listed below are usually easy to find in local garden centers and have proven reliable in Florida landscapes.
- Abelia x ‘Rose Creek’ Rose Creek Abelia, low mounding growth habit reaching 2-3’ tall and 3-4’ wide, green foliage, new reddish stems, large clusters of white flowers
- Abelia x grandiflora ‘Hopley’s Lemon Zest™’ Lemon Zest Abelia or Miss Lemon™ Abelia grows 3-4’ tall and wide, has yellow and green variegated foliage, light pink flowers
- Abelia x grandiflora ‘Confetti’ Confetti® Abelia, matures at 3’ tall and wide, new foliage has pink, white, and green variegation and mature foliage is green and white variegated, pink and white flowers
- Abelia x grandiflora ‘Kaleidoscope’ P.P.#16,988 Kaleidoscope Abelia, compact growth 2-3’ tall by 3-3.5’ wide, gold and pink new foliage that matures into gold and green variegation, white flowers
All abelias perform best in full sun to part shade and have low water requirements once established. They are not salt tolerant, so avoid planting in coastal landscapes or in areas where salts are an issue. Abelias have few pest problems, but aphids have been known to feed on new growth – avoid over fertilization.

Few plants seem to signify the freshness of spring quite as well as daffodils. The name “daffodil” is derived from “addodell” a variant of Asphodel (a plant of the Asphodelus genus.) In historical documents and the common language of 16th century Europe, the term “daffodil” referred specifically to the wild daffodil, Narcissus pseudonarcissus.
The derivation of the Latin narcissus is unknown. It is frequently linked to the Greek myth of Narcissus, who was rumored to be so obsessed with his own reflection that he died while gazing at himself in a pool of water. From the location of his death sprang the narcissus plant. Another Greek myth finds Persephone, daughter of the goddess Demeter, lured to her doom by the God Hades while picking a narcissus. Therefore the plant is perceived as a symbol of vanity in some Western culture.
Others attribute the plants’ name to its narcotic properties. One translation of the Greek name is “I grow numb!” All narcissus species contain the alkaloid poison lycorine, mostly in the bulb but also in the leaves. Members of the Amaryllidaceae family contain a unique type of alkaloids. They are responsible for the poisonous properties of a number of the species. Of the 200 different chemical compounds found in this plant family, at least 79 of them can be found in narcissus.
Daffodils are a popular potted plant for cut flowers, but also make attractive naturalized groundcovers in gardens and around trees, providing color from the end of winter through late spring. If the narcissus blooms on Chinese New Year, it is said to bring wealth and good fortune throughout the year. The flower color varies from white through pinks and yellows to deep reddish-orange with multiple petal forms. Hundreds of cultivars are available.
Planting dates vary according to geographical location, but the bulbs are usually planted in the fall when the soil is cool. Daffodils grow well in full sun or light shade, with the blooms lasting longer when protected from the noon day sun. When selecting a location for planting, it should be noted that the individual flowers will face the sun.
Pre-chilled bulbs should be planted in 6-8” deep holes with a tablespoon of slow release fertilizer added to the soil directly under the bulb and with 4-5” of soil covering the bulb. Watering throughout the winter will be necessary if rains are infrequent. After flowering, the daffodils need to be fertilized and watering should continue. The foliage will naturally turn yellow and die as stored food is restored to the bulb.
Division, transplanting and collection for forcing potted plants can be done after all the foliage has declined. To force Daffodils to bloom at varied times in a container the dried bulbs will need to be stored at a 45° F temperature for 4-6 weeks prior to being placed in the sun to grow.
The bright, cheery Daffodil flowers are beginning to bloom now and will continue as Easter approaches, reminding us that spring really is coming.

Although it is quite cold outside right now, spring is just around the corner. Many of us have perennials we enjoyed all summer and fall, and have been faced with their ugly dead stalks all winter. Perennials that are meant to die to the ground each winter look ugly and decayed after the first frost. For many perennials, the stalks have been left up and allowed to slowly die, allowing nutrients to be slowly translocated to the root system.
Many perennials, such as hibiscus species, hydrangea, salvia species, firebush (Hamelia patens), rudbeckia, echinacea, lantana and others still have a large amount of starch stored in their branches, even after the first frost. Although it was very tempting to remove these unattractive reminders of the beautiful spring gardening season, hopefully you waited to allow the starch to translocate (move) down to the root system.
Now through early March is the time to remove those unsightly dead branches to living tissue. To determine if there is “life” left in those burned and singed stems, just scratch off the top layer of the stem. If any nutrients remain in the stem, it will be green or yellow where the scratch was made. Another good way to determine if it is a good time to cut perennials back, since coastal and inland locales differ climactically, is to observe the beginning of new growth and trim at that time. If it is brown it’s dead, cut it back!

Sedum rupestre ‘Angelina’ is an evergreen perennial that adds some pizazz to winter landscapes. This low growing plant performs well in sunny, well-drained spots in the landscape but will also tolerate some shade. In the summer, the foliage is a brilliant chartreuse but after a few cold snaps it takes on a coppery bronze tinge that brightens up winter landscapes.
Angelina sedum is an easy to grow groundcover that contrasts nicely with deep greens, burgundy, or black foliage. It grows well along the ground or in containers where it may drape down the sides. It roots where the stems touch the ground, but is not aggressive and can be easily divided and transplanted into new garden sites or shared with friends.
Small, delicate yellow flowers appear in the late spring or early summer but the plants are mostly grown for foliage texture and color.

Although it seems like summer outside, especially with such warm weather the week before Thanksgiving, winter temperatures will be coming. Possibly sooner rather than later. Perennials that are meant to die to the ground each winter look ugly and decayed after the first frost. Faced with such unattractive plants, most gardeners are inclined to cut them to the ground right away. That action might be a mistake.
Many perennials, such as hibiscus species, hydrangea, salvia species, firebush (Hamelia patens), rudbeckia, echinacea, lantana and others still have a large amount of starch stored in their branches, even after the first frost. Although it is very tempting to remove these unattractive reminders of the beautiful spring gardening season, it is better to wait to allow the starch to translocate (move) down to the root system. The time that this takes varies by plant species, but can be as late as February.
To determine if there is “life” left in those burned and singed stems, just scratch off the top layer of the stem. If any nutrients remain in the stem, it will be green or yellow where the scratch was made. If it is brown and dead, it is safe to prune the perennial back.
If you can stand to wait, allow those unsightly stalks to remain until February. If they contain any plant nutrients this will give the plant some energy during the winter months. This is not possible in every situation, but following this practice will bring stronger flowering perennials next season!

Fall is a good time to evaluate your landscape, learn from what has and what has not worked and formulate plans to improve your landscape.

Before your lawn and landscape plants go dormant, do a walk through of your landscape, make notes if necessary and visually inspect the plants. You get to see the plants that did great as well as the plants that were not so successful. You can make decisions on which plants to do away with, which to keep, which that might benefit from being moved to a more appropriate location, etc.
As you inspect your landscape, ask yourself questions. You can easily identify problem areas in the lawn now. As you identify problem areas in the lawn, attempt to determine why those areas aren’t doing so well. Begin formulating plans for correcting/improving those problem areas. Decide if renovating and replanting with grass is your best option. Or, something other than grass may be the best option, particularly if there is a history of problems with grass in a specific location.
It may be time to remove and replace an older, declining plant with something new. There may be a plant that hasn’t performed up to par but that would do better if moved to a more appropriate location – fall is a great time to relocate plants. Now is a good time to take a soil sample and take the guesswork out of liming or fertilizing. The UF / IFAS Extension Office in your County can provide information on how to have your soil tested.
This only represents a few ideas related to evaluating your landscape. You’ll probably think of many more as you’re out in the landscape. Taking notes will allow you to implement your ideas later.
Not only is fall a great time to enjoy the outdoors, there’s much that we can learn from our own landscapes this time of year. We can gather Information that will allow us to improve our own landscapes.
