    Conditions for Growth

    The tree excels in the loam soil of the Riverside Grove, grown in full sun with intense heat (an good irrigation) during the summer and cold nights during the winter.

    Growth Rate and Size

    A painfully slow grower, the trunk increase vertically at just 5-6 inches per year for the first 10 years as it fills into a massive girth, after which the trunk will grow at a faster pace eventually reaching 50 feet. The leaf is a different story, reaching its a massive scale quickly.


    The Sabal causiarum has a solitary trunk covered with persistent sheath split fiberous bases showing and when mature and/or free of leaf bases reveal a grey, smooth, close rings, massive diameter with saxophone shape at base stem pattern. The leaf is 6 feet long, deeply folded and arched, 3 feet wide (folded) and about 4 feet long , costapalmate, deep green with induplicate splitting along adaxial ridges. The petiole is wide, 7, 8 feet or longer. It is unarmed, with no teeth but sharp margins. Flowers are cream white-yellow and reach out on multi-bract inflorescence, and are quite the attraction for bees happy to aid in their pollination. Fruit from this species is 1/3 inch, round, black when ripe.
