We all seem to plant the basic herbs like basil, rosemary and parsley. What suggestions can you offer for more exotic herbs that I could add to my garden to spice things up both for cooking and adding interest/beauty to my landscape?

I think lemon grass (Cymbopogon citratus) would be a good candidate for landscape interest and culinary use; it is even reported to have more mosquito control attributes than citronella. It is a warm season annual grass that grows quickly and is used in teas and Thai cooking to add a lemony flavor without the acidity of lemon juice. Stevia is a natural sweetener option for those trying to avoid added sugar. There is also a mint called Berries and Cream which merges peppermint with berry flavors for a unique twist on the traditional mint options.

Golden lemon thyme (Thymus x citriodorus) adds good citrus flavor to dishes and tea. The 8-inch tall cultivar ‘Aureus’ makes a good edging paired with Salvia officinalis ‘Icterina’. The chartreuse ‘Lime’ shines in dark garden corners.
Red shiso (Perilla frutescens) has frilly garnet red leaves, edible flowers and a spicy cinnamon/clover flavor. Papalo (Porophyllum ruderale) has a taste between arugula and cilantro. Plant once cilantro bolts to seed. Steely blue foliage up to 5 feet tall.

A plant that is often included with the popular herbs that gardeners know at Shady Hill is the scented geranium. It doesn’t look anything like a garden geranium, but it has a wide range of fragrances, as well as varying leaf shapes and colors. The fragrances may be lemon, rose, pine, ginger, lime, balsam or apple. It can be used in cooking and also in potpourri and sachets. Some scented geraniums are upright, some cascading, but all are unique and quite easy to grow. They are ideal for planters.

Onion or garlic chives can be grown and cut for use in potatoes and eggs. We also have five different types of mint that can be grown and used for mojito, flavoring water and teas. Some varieties such as pineapple mint are attractive and add beauty to the garden. Thymes such as English and lemon can be used in pasta and in marinades for grilling. A good marinade for meat can be made from thyme, rosemary, sage, Italian olive oil and pepper.
My split-leaf Japanese maple tree is 15 to 20 years old, about 7 feet high and about 10 feet wide. It is overtaking the corner of the yard. Can I trim it, and at what time of the year?
Is there an overall rule about when to pinch back my leggy plants?
I have a hoya houseplant that has been growing happily for eight years. It had flowers when I received it, but it hasn’t bloomed since. What am I doing wrong? Can I get it to flower?
