Its flower, somewhat less famous for obvious reasons, has five elongated petals and the same number of sepals that give it a lot of showiness and a notable contrast in relation to its leaves, which are also usually very striking.

The soil where it lives should combine equal amounts of peat, coarse sand and leaf mulch.

In simple terms: a good substrate, rich in nutrients (organic matter) and good drainage, guarantees, together with optimal irrigation and good natural light, that this plant flourishes throughout the year.

2. It deposits substrate (worm humus, decomposed manure …) inside the hole.
3. Lightly water the hole and deposit the seeds or seedling.
4. Water lightly again.

Pruning: How can we do the Flor de Oca?

It does not require strict or regular pruning. But it is important to carefully remove the dry leaves, in order to prevent amorphous growth.

Our recommendation is to use drip irrigation or water with a watering can. In this way we will prevent the soil from flooding and the origin of fungi or other diseases.
