Cheap and Easy to Tend seasonal plants for my garden tubs

I'm going for begonias for shady spots and geraniums (sented leaf ones) for sunny pots. I always pot up a few nice grasses to mingle with them. I find one variety of anything often (to me) looks more spectacular than a mix!

Begonias, petunia, geraniums, impatient, nasturtiums

Last year I had Tidal Wave Petunias, Osteospermum, Busy Lizzies and Fuschias in groups of pots. If you like profusion I would recommend them. They flowered right up to the first frosts.

You really can't beat Pelargoniums for being neglected.
The range of hybrids has increased.
I get mine in the local market .
If you are careful-you can winter them in your kitchen then as they will become leggy give them a cut and plant out after the frosts

Most other plants are too tender .
I always put my cooled used tea bags on top of the soil to keep moisture in .
I've got a huge variety of plants in my pots and all of them need watering almost daily .

I've had beautiful displays of iris germanica but you're left with just leaves for the rest of the year .
I recommend the variegated one.
Irises aren't thirsty plants .
Lavender is easy .After a few years it tends to become woody and ugly.
Rosemary is another idea .
