Cassia Fistula tree seeds – 5 Seeds
Cassia can be a delight in the fall landscape because it is covered with cheerful yellow flowers when few other plants are blooming. Plus, cassia provides interesting foliage during other times of the year.
Another benefit of cassia plants is that they serve as larval host plants for three types of Florida butterflies—cloudless sulphur, sleepy orange, and orange-barred sulphur.
All cassia trees prefer a sunny location with well-drained soil.
Stake your tree – it will protect it from strong wind or extreme leaning like the surattensis pictured.
Add organic peat humus or top soil to the hole when you plant – or, better yet, a combination of one of those and composted cow manure.
Next to no trimming is needed on any of these trees, though you can prune for bushiness, shape or post-winter clean-up – do this in late March or early April when we’re past the threat of frost.
Fertilize each of the cassias with a quality all-purpose granular fertilizer (supplement with bone meal to promote bloom) in spring, summer and fall.
Seed pods can form after flowering…remove them or leave them on. Keep these trees on a regular watering schedule.
Cassias can go quite close to the house – desert cassia as close as 4 or 5 feet, surattensis as close as 6 to 8 feet, and fistula 8 feet or more.
These plants aren’t suitable for growing in containers.
