Bromeliads are an interesting group of plants with over 800 varieties. Some bromeliads are epiphytic (grow on trees or other objects for support) while some require soil for their roots – including the most well-known member of the family – the pineapple plant (Ananas comosus). Bromeliads are very easy to grow in warm and temperate climates, and have an amazing range of foliage and flower shapes and colours. Most bromeliads grow in a rosette form with a central well, and their unusual flowers grow from the central well.
The blade leaves of bromeliads funnel a lot of water into the central well, providing moisture for insects and other small creatures in times of drought, and the insects provide organic matter to fertilise the plants. This regular supply of food and water also attracts frogs.
If you like having frogs in your garden, try growing some bromeliad genera with soft, leathery, broad leaves – for example Aechmea, Neoregalia, Vriesea or Bilbergia, which grow best in part shade around the base of trees. These bromeliads rely mostly on their central well for water and food, and use soil mainly for support. The rosette of leaves also provides a hiding place for frogs.
Plant in autumn in warmer areas or spring where winters are cold. Grey-leaved bromeliads absorb moisture from the atmosphere and do not need soil, and bromeliads with heavily barbed leaves do best in acidic soil in full sun.
It has been raining for the past ten days and I don’t want to seem ungrateful after so many years of drought but, I am anxious to get out in the garden again and get my hands dirty. At least the frogs are thoroughly enjoying the weather.
I really enjoyed visiting the Frogs Australia Network website, as it contains information about an amazing number of frogs, and you can listen to individual frog calls to aid in identification.
Arthur from the Frog and Tadpole Study group (FATS) has informed me that the mottled frogs are “Bleating Tree Frogs”. We have heard these frogs in previous years but had no idea what they looked like. We thought we had lost them when one of our dams dried up during the drought, and our evenings became much quieter, so we are pleased to see that enough survived to restock their species.
Once the majority of the frogs had left the pool, we rounded up the few remaining stragglers and transferred them to our small frog pond. Among the stragglers were this tiny frog, and a similar froglet with a tail. Despite a thorough search of the pool, we were unable to find any more of this variety. I have never seen such a tiny frog before. He is sitting beside a 5¢ piece on the rim of the frog pond.
After many years of drought, we had a lot of rain earlier this year. It was impossible to keep our pool chlorinated, so we waited until the sky cleared before attempting to clean the pool. To our surprise we found the pool contained many hundreds of tadpoles. Frogs are very welcome on our property because they eat insects and spiders. They are also a sign of a healthy environment. Many pesticides and herbicides are toxic to frogs and tadpoles.
The tadpoles were feeding on the algae on the sides of the pool, and looked quite healthy. Apart from providing some shade for them over part of the pool, and providing some ramps for froglets to get out of the pool, we left them to do what tadpoles do best. An old window screen prevents them from being sucked into the filter when we run the pump. I haven’t fed them because I haven’t had any lettuce growing, and I didn’t want to feed them lettuce that could contain systemic pesticides.
There appears to be three types of tadpoles, one brown, one black, and a very shy type that is a pale, almost translucent, olive. These tadpoles don’t look the same as the small green tree frogs that bred in our small frog pond, as they were quite green by the time their tails had been absorbed (see below).
The first to become froglets were the brown tadpoles; the other two types still have tails.
These mottled frogs with a dark stripe down each side, aren’t particularly nervous around humans and will allow me to get close enough to photograph them. In sunlight, the tops of their heads look almost like burnished copper, but at other times they look grey-brown. It appears that these froglets belong to the tree frog group because they have no trouble climbing the tiles at the edge of the pool. I spotted one of them hiding in a Birds-nest Fern the other day but most of the frogs are treating our backyard like Club-Med, and spend the day lolling around the pool. I have no idea what kind of frog they are, and would be grateful if someone could enlighten me.
