Breathtaking Queen's Wreath

By Onika Amell, tropical flower specialist

Q: I've just moved from Virginia to Sarasota, Florida. I'm looking for a vine similar to Wisteria to grow in my new garden. I've so enjoyed my Wisteria vine and I'm hoping to find something equally spectacular for my FL garden. Truth is, I'm getting older and won't be able to keep up with the hard-core maintenance Wisteria needs to keep it in under control. Is there a similar vine you can recommend that is just as showstopping as Wisteria?

A: The vine that immediately comes to mind is Petrea Volubilis or Queens wreath. It looks similar to Wisteria, and though a fast and strong climber, it's not invasive or destructive at all. An occasional pruning is all it will need to maintain it. Much like Wisteria it gives a glorious show of flowers when spring arrives. Masses of long, mauve flowers will continue to appear on and off in summer with another burst of flowers in the fall. Flowers are up to a foot in length!
Hummingbirds, bees, and butterflies will all be impressed with you for growing this charmer.
Snip off the gorgeous flowers, put them in shallow bowls of water around your home and be the envy of all your friends and house guests!
This vine prefers the warmth of Zone 10 to thrive, but it will survive in areas of Zone 9B when it borders zone 10A, especially if it's placed in a protected area. It grows best in full sun but will tolerate part shade. It's great for coastal gardens and once established, it has good drought tolerance, medium salt tolerance, and good wind tolerance. It has no major pest problems, which is always a bonus.
Grow and shape it as you like: a large bush, a small tree or a breathtaking espalier. Some people plant Petrea vine by a tree to create that much sought-after ethereal wisteria effect. This is no doubt a very charming vine and a must-have for those who are in love with Wisteria but scared of its vigorous growth and ongoing maintenance.
For Wisteria lovers we also recommend its spectacular tropical relative Millettia reticulata - Evergreen Wisteria.

Secrets of Happy Bougainvilleas

Q: When I visited Hawaii I saw their everblooming bougainvilles, flowering non-stop! How come our bougainvilles in Florida are not flowering as much? Is there any special secret to make them bloom?

A: Bougainvilleas prefer drier climate and especially drier summers. Florida summers are rainy and humid. The steaming greenhouse conditions are favorable for most tropical plants (except desert plants like most cacti). Bougainvilleas also grow vigorously in Florida heat and frequent rains, but most cultivars prefer dryer conditions for profuse flowering. These are a few tips that can help you grow happy Bougainvilleas and enjoy their showy flowers even in humid climates:

- In Florida, Bougainvilleas bloom mostly in Winter. If you are a snowbird, this plant is definitely for you!
- Choose sunny, dry, and elevated location for Bougainvilleas, never a low spot and never a shade spot. Give it as many hours of sun as possible.
- Use only well-draining soil. Usually, sandy soils work well when mixed with some compost. If your soil is too heavy, add soil conditioners like perlite, bark, sand.
- Take advantage of cultivars that are well adapted to humid climates: Dwarf Everblooming Pixie, Thornless B. arborea.
- Remember Bougainvilleas are the easiest and the most rewarding potted plants.
- Use bloom boosters along with well-balanced slow release plant food. We recommend these: Pink-N-Good flower booster and smart-release granulated Tropical Allure.
- Do not overwater and keep the plant on a dry side.
