About This Plant

Hoya Pubicalyx is native to the Philippines, where it grows in warm, humid, bright forest conditions. It produces lance-shaped, dark green, waxy leaves with irregular silver speckles across the surface.

It is one of the easiest Hoyas to get flowering. Many Hoyas grow for years without flowering. Hoya Pubicalyx produces the mature vine sections needed for blooming quickly, and then flowers reliably once established.

Safe for cats and dogs. The ASPCA confirms Hoya spp. is non-toxic to cats and dogs. Pubicalyx is pet-safe. The Hoya Pubicalyx Silver Splash is the same species with much heavier and bolder silver splashing on the leaves.

It fills a hanging basket or trellis within one season. It is a good choice for someone who wants a Hoya that visibly progresses and fills a space rather than one that grows slowly.

Winter Slowdown

Growth slows or stops from November onward. Any existing flower peduncles must be left completely undisturbed. The dark silver-speckled leaves remain attractive through winter even without new growth. No fertilizer until spring.

Toxicity

Non-toxic to cats and dogs, confirmed by the ASPCA (Hoya spp.). Safe for homes with pets and small children.

Pests

Mealybugs are the primary pest, appearing in the leaf axils along the fast-growing vines. Check each stem joint when watering. Scale insects can appear on older woodier stem sections.

Other Plants You Might Like

Not sure this is the right fit? Here are three other plants our customers love. All ship across Canada and thrive in homes.

Hoya Pubicalyx Silver Splash. Same species, heavier silver.

For the same fast-growing, reliable-blooming Hoya with much bolder and heavier silver splashing that almost covers the entire leaf surface, the Hoya Pubicalyx Silver Splash.

Hoya Australis. White flowers, reliable bloomer.

For another reliably blooming Hoya that produces white fragrant flower clusters and grows vigorously, the Hoya Australis.

Hoya Krimson Queen. Variegated, slower-growing.

For a Hoya with cream and pink variegated edges and a more decorative foliage character at the cost of slower growth, the Hoya Krimson Queen.

Common Questions

How do I get Hoya Pubicalyx to flower?

Bright indirect light for most of the year is the primary requirement. At least three to four hours of bright indirect light from an east-facing window. The vine needs to be established with mature sections, so give it at least one full growing season before expecting flowers. Never cut old flower stalks, which are the permanent reblooming points.

The flowers are dark red-maroon but I expected pink. Is this normal?

Yes. The flower colour of Hoya Pubicalyx varies depending on the specific cultivar and the amount of light the plant receives. More light tends to produce deeper, richer red-maroon tones. Less light tends to produce more pink-toned flowers. Both are normal and healthy.

Is Hoya Pubicalyx safe for cats and dogs?

Yes. The ASPCA confirms Hoya spp. is non-toxic to cats and dogs. Safe for homes with pets and small children.

The silver speckles look less visible on new leaves. Why?

New leaves on Pubicalyx sometimes arrive with less visible silver speckles before the wax layer fully hardens. The speckles become more visible as the leaf matures over two to three weeks. If older established leaves are also losing silver visibility, the leaves may need cleaning: dust on the waxy surface dulls the silver contrast.

Can I propagate it and how fast do cuttings root?

Yes. Take a stem cutting with at least one node and one or two leaves. Allow the cut end to callous for an hour then place in moist sphagnum moss in a warm, bright spot. Pubicalyx roots faster than most Hoyas given its vigorous nature, typically within two to four weeks in good conditions.

Good to Know

Sun: Indirect

Bright indirect light is needed for vigorous growth and reliable flowering. An east-facing window giving several hours of bright indirect morning light is ideal.

Light: Medium to bright indirect

A spot near an east-facing window works best year-round. From October to February in Canada, keep it as close to the brightest available indirect light as possible. Inadequate winter light reduces flowering the following season.

Water: When top 1-2 inches are dry

Water when the top one to two inches of soil feel completely dry. Every ten to fourteen days in spring and summer, every three to four weeks in Canadian winter.

Humidity: Low to moderate

Handles the dry forced-air heating of Canadian homes well. No humidifier required.

Pet Friendly: Yes

Non-toxic to cats and dogs, confirmed by the ASPCA (Hoya spp.). Safe for homes with pets and small children.

Pro Tip

Hoya Pubicalyx rewards preserving flower stalks. Once a peduncle has produced its first bloom, it will continue producing from the same point for the entire life of the plant. Mark each peduncle. Over 2-3 years, a Pubicalyx will have multiple marked peduncles producing staggered bloom cycles.
