I'm new to gardening and trying to grow things that are good for novices. I also have a 3-year-old daughter and she's interested in plants so I'd like to show her something growing from seed to flower.
There's a wide, shallow planter in our garden that was left behind by the previous owners. What's a good seed to plant now that will fill a pot like this and is fairly easy and reliable? I can move the planter to any side of the house so it can be in full sun, partial shade etc.
I live in the south west so it's fairly wet and warm. I've already planted nasturtiums, forget-me-nots and California poppies, and we have established fuschias and hardy geraniums. We've got a few dahlias in pots already.
