How Can I Choose Plumeria Varieties for Cold Climate Gardens?
Introduction
Plumeria, the epitome of tropical elegance with its sumptuous blooms and evocative fragrances, is not usually associated with cold climates. However, thanks to modern cultivation techniques and a better understanding of the plant’s needs, it’s now possible to enjoy Plumeria even in colder zones. This comprehensive guide will walk you through how to choose Plumeria varieties that can flourish in a colder environment.
Challenges of Growing Plumeria in Cold Climates
1. Temperature Tolerance
Plumeria plants typically thrive in temperatures ranging from 65-90°F (18-32°C). Cold temperatures can cause the plant to go dormant or even suffer from frostbite.
2. Reduced Sunlight
In colder regions, sunlight can be less intense and less consistent, which can affect Plumeria’s flowering.
3. Dormancy Period
Plumeria plants may experience a more extended dormancy period in colder climates, potentially affecting the growing and flowering phases.
Factors to Consider When Choosing Varieties for Cold Climates
1. Cold Hardiness
Look for varieties known to have better cold tolerance. Always check hardiness zone recommendations when selecting your plants.
2. Growth Habit
Opt for Plumeria varieties that are compact or suitable for pot culture. This will make moving the plants indoors during the coldest months easier.
3. Flowering Time
Choose varieties that have a shorter time to first bloom. This ensures you can enjoy their flowers before the cold sets in.
4. Fertilization: Feeding Your Plumeria
Type of Fertilizer Recommended
A balanced fertilizer with micronutrients is best for plumeria. The optimal N-P-K (Nitrogen-Phosphorus-Potassium) ratio might look like 11-11-13 or similar.
Fertilization Schedule
During the growing season, follow the manufacturer’s instructions for fertilization. As winter approaches, reduce the feeding schedule.
Varieties Suitable for Cold Climates
1. Plumeria rubra ‘Everlasting Love’
This variety has good cold hardiness and can withstand temperatures slightly lower than other Plumeria types.
2. Plumeria obtusa ‘Dwarf Pink Singapore’
It is a compact variety with pink blooms, suitable for pot culture, making it easier to move indoors during winter.
3. Plumeria pudica
This variety is noted for its more extended flowering season, giving you a better chance of seeing blooms even in colder conditions.
4. Plumeria ‘Slaughter Pink’
A cold-hardy variety with striking pink blooms, ‘Slaughter Pink’ can tolerate cooler temperatures better than other varieties.
5. Plumeria ‘Aztec Gold’
Renowned for its cold tolerance, ‘Aztec Gold’ offers golden-yellow blooms and a shorter time to first flower.
Conclusion
While Plumeria plants are best suited for tropical environments, choosing the right varieties and taking some extra care can enable you to grow them successfully in colder climates. From selecting cold-hardy varieties to adjusting feeding schedules, you can enjoy the tropical allure of Plumeria even if you don’t live in the tropics.
